Title: Near-neutral chlorine dioxide bleaching of pulp
Inventor: JIANG ZHI-HUA
IPC: D21H21/32
Filed: 2007-02-12
Abstract: Final chlorine dioxide bleaching of lignocellulosic materials is most effective at a near-neutral pH but present industrial practice typically targets a final pH of between 3.5 and 4.0 because of the difficulty in achieving and maintaining near-neutral pH cost effectively. The in situ formation of bicarbonate before the addition of chlorine dioxide provides a way of maintaining the required near-neutral pH. Near-neutral final chlorine dioxide bleaching also produces a bleached pulp that is in a state that responds more effectively to fluorescent whitening or optical brightening agents.

Inventor: LAMARCHE FRANCOIS J
IPC: G21B1/15
Filed: 2008-10-20
Abstract: The basic idea of creating conditions of high density and/or high temperature (reaching the Lawson criterion) to produce cheap Nuclear Fusion energy is a valid one, but one has to devise many alternate mechanisms to reach this criterion to haste success. This invention describes an apparatus that accelerates macroscopic pieces of matter held together at high density as either a solid speck or a liquid drop, and fires them at a solid target having a special carved shape, to achieve the Lawson criterion over large spatial regions. The extent of these regions is optimized to produce a break-even in the energy balance. The resulting energy production is commensurate with that of a small Power Plant.

IPC: G06T15/70
Filed: 2007-11-08
Abstract: A method for authoring and displaying a virtual tour of a three-dimensional space which employs transitional effects simulating motion. An authoring tool is provided for interactively defining a series of locations in the space for which two-dimensional images, e.g., panoramas, photographs, etc., are available. A user identifies one or more view directions for a first-person perspective viewer for each location. For pairs of locations in the series, transitional effects are identified to simulate smooth motion between the pair of locations. The authoring tool stores data corresponding to the locations, view directions and transitional effects for playback on a display. When the stored data is accessed, a virtual tour of the space is created that includes transitional effects simulating motion between locations.  The virtual tour created can allow a viewer to experience the three-dimensional space in a realistic manner.
